Definitions

  • the invention relates to a method for installing a road surface.
  • the document US 5568992A describes such a method with all features of the preamble of claim 1.
  • the screed plate of the Ausziehbohle is adjusted relative to the planum automatically relative to the screed plate of the base screed to the respective correct altitude corresponding to the respective angle of attack of the screed, so that no longitudinal steps arise in the pavement.
  • the working width is varied by moving the Ausziehbohlen to the base board.
  • the attack angle of the screed relative to the plane may affect or change the lining thickness, which requires adjusting the height position of the trailing edge of the screed screed plate relative to the trailing edge of the screed screed plate.
  • the height adjustment devices are actuated in the Ausziehbohle.
  • a varying in the transverse direction covering thickness is adjusted by different height positions of the tow points of the Ceiholme the screed on the paver.
  • the invention has for its object to provide a method of the type mentioned above, which can reliably hold the transverse position of the transition with respect to the base pile, and requires only the processing of a minimum amount of information.
  • the transverse position of the transition is first determined by, for example, the height position and / or bank of the screed plate of the Ausziehbohle be adjusted so that the transverse position is at the desired location relative to the base board. Based on the specified transverse position, the height difference is measured perpendicular to the planum and converted to a setpoint. In a required during installation change of the working width, this height measurement is still performed and only the resulting from the change deviation from the target value is used to make a height adjustment of the screed of the Ausziehbohle so that the transverse position is held stationary. This results in a reliable method for maintaining the lateral position of the transition, whereby only a minimal amount of information is obtained, evaluated and processed, namely only the height difference.
  • the height difference and / or its deviation is measured with a measuring member of a height measuring device fixed to the base pile.
  • the measuring element measures independent of the current displacement position of the Ausziehbohle on the base board and provides directly required for operating the height adjustment of the Ausziehbohle information to automatically hold the transverse position can be fixed.
  • the height difference and / or its deviation is measured with a height measuring device having a measuring member which is height-adjustable relative to the fixed measuring point on the base screed and thus directly provides the height difference information by moving along with the extension screed relative to it slides shifted reference line, wherein it is held in the sliding direction of the Ausziehbohle relative to the base board.
  • the parallel to the screed plate Ausziehbohle reference line moves when moving the Ausziehbohle relative to the sliding thereon measuring member and moves it in the height direction, so that the height difference is tapped directly.
  • the height difference is expediently measured at or near the end of the screed plate of the base screed associated with the screed.
  • measurement inaccuracies are largely avoided, which could be caused, for example, by deformations of the relatively movable components.
  • this is useful in a screed whose Ausziehbohle is located at the rear of the base board, because in this case, the transverse position of the transition is to be kept appropriate at this end of the Glättblechs the base board.
  • the height difference can be measured without contact by means of at least one measuring element designed as an electronic height sensor and converted into an actuating signal for a height adjustment device in the extension plank.
  • the electronic height sensor can operate on optoelectronic, radar, ultrasonic or other basis.
  • the height measuring device can be designed such that the measured deviation is translated or amplified in order to operate the height adjustment of the Ausziehbohle better even with a small change in the working width and / or the angle.
  • the linear velocity of the displacement of the Ausziehbohle in the sliding direction parallel to the base board and the linear velocity of the height adjustment of the screed of the Ausziehbohle at least approximately perpendicular to the planum taking into account the set angle of the shoulder or a geometric angular function of this angle, preferably the tangent of the angle, so coordinated so that the transverse position of the transition is maintained even with only a slight change in the working width.
  • a not fully corrected by the automatic height adjustment of the screed of the Ausziehbohle deviation from the target value of the height difference can be corrected manually or remotely.
  • the driver or the operator on the screed can detect a change in the working width and / or a change in the angle of a lateral bleeding of the transition between the road and the shoulder directly by visual inspection and then intervene so to speak overriding.
  • the transverse position of the transition is held substantially at the Ausziehbohle associated end of the screed of the base board to avoid that otherwise accumulates in a possibly resulting between the ground pile and the Ausziehbohle dead space stowed, causing disruption could result in the surface of the road surface.
  • the Fig. 1, 3 and 5 each show a driving in the working direction R road paver F when installing a road surface covering M with a working width 35, which is adapted to local conditions variable.
  • the paver F tows at tow points 2 with towbars 1 on a B (bituminous material or concrete property) a screed E, which has a base board G unchangeable screed width and two on the base board G rearwardly arranged Ausziehbohlen A, for changing the working width in one Sliding direction Z are parallel to the base boom G displaced.
  • the built-in road surface M consists of a flat lane 3 certain width 34 (alternatively with a roof profile) and a lateral, downwardly inclined shoulder 4 a width 33, which may vary depending on the working width 35.

  • Fig. 7 Screed E shown in a rear view has a base beam G with two substantially symmetrical base screed parts G1, G2, which are connected in a lying in working direction R joint 9. Thanks to the hinge 9, the base board parts G1, G2, as shown, can be aligned with each other to form a flat surface of the roadway 3, or bend relative to each other (not shown) to form a roof profile. If only one side of the roadway 3, a shoulder 4 installed is, the opposite Ausziehbohle A can install a flat edge region of the roadway 3. Alternatively, 3 shoulders 4 can be installed on both sides of the roadway.

  • the guide body 21 With fully pushed-Ausziehbohle A, the guide body 21 can be moved to the support 20, so that a total displacement displacement of the Ausziehbohle A results approximately equal to half the plank width, and thus a maximum working width 35 corresponding to twice the plank width, assuming the Ausziehbohle A is approximately as wide as each base section G1, G2.
  • the Ausziehbohlen-smoothing plate 7 is attached to a box-like frame 27, preferably interchangeable, and with this about a pivot joint 26 by means of actuators 29 bankable.

  • a reference line L is, for example, a ruler 30 mounted on the rear edge region of the screed screed plate 7 or on any position of the frame 27.
  • the measuring member 32 determines a deviation from the setpoint, since the inclined Ausziehbohlen-smoothing plate 7 moves in the sliding direction Z parallel to the base screed plate 6 and thus the measuring element 32 now scans another, deeper point of the reference line L.
  • the deviation is converted into an actuation signal for the drive 23 of the height adjustment devices 22 to raise the intermediate frame 24 immediately according to the deviation, so that when moving the Ausziehbohle A, the transverse position of the transition 5 at the end 42 of the base screed Glättbleches 6 is held.
